Abstract

L'invention concerne une cellule électrochimique destinée à des applications telles que les cellules à combustible, ou les détecteurs de gaz de cellules électrochimiques utilisés pour la détection d'espèces de gaz prédéterminées dans les environnements contenant ou susceptibles de contenir ces gaz. La cellule électrochimique utilise un liquide ionique comme agent électrolytique, accomplissant ainsi une plus grande plage de températures et d'états opérationnels, par rapport aux cellules électrochimiques utilisant du carbonate de propylène ou un autre agent électrolytique classique.
